Critical points occur when

, which happens for

and

.
Check the sign of the second derivative at each critical point to determine the function's concavity at that point. If it's concave (

), then a maximum occurs; if it's convex (

), then a minimum occurs.
You have

and so


This means a maximum of

and a minimum of

.
